How to Tell If You Have Mold Behind Walls or Under Flooring

Mold doesn’t always grow in plain sight. In many cases, it spreads behind walls or beneath flooring, causing damage long before homeowners realize there’s a problem.

Warning Signs of Hidden Mold

You may have hidden mold if you notice:

• A musty or earthy odor that won’t go away
• Peeling paint or bubbling drywall
• Warped floors or loose tiles
• Unexplained allergy-like symptoms
• Past water damage from leaks or flooding

Mold thrives in dark, damp spaces, making wall cavities and subfloors ideal environments.

Why Hidden Mold Is Dangerous

Hidden mold can:

• Weaken structural materials
• Trigger respiratory issues and allergies
• Spread rapidly if moisture remains

Ignoring these signs allows mold colonies to expand, increasing cleanup costs and health risks.

How Professionals Detect Mold

Certified restoration teams use:

• Moisture meters and thermal imaging
• Air quality testing
• Controlled inspection openings

This ensures mold is located accurately without unnecessary demolition.

Don’t Ignore the Signs

If your property has had water damage even months ago mold could already be growing. Early detection can save thousands in repairs.
